What is actually a concrete release agent?
A concrete release agent is a material placed on the construction template just before the concrete is added so the design does not stick to to the concrete covering right after pouring, isn’t effortless to dismantle the cast or influences the finish of the concrete covering. Its principal role in the template and the concrete surface to create a motion picture that will probably be separated from the two can also be referred to as an separation agent.
A water-based release agent is surely an essential supplementary within the release agent and can alter the water-based release agent stream and levelling; its primary feature is actually stability to microorganisms and enzymes, which can reduce the cost of raw materials. A water-based form release agent can be used in moulds and products functional processing additives; in the rubber, plastic, and Jinsu processing industry, manufacturing form items aren’t just to be able to let the form release to boost productivity and lengthen the life of the cast utilize. And can make the item thoroughly clean, size qualified, and lower the creation of scrap, which is an essential additional vital to moulds and products – concrete additive.
Concrete release agent plays an essential role in modern building building; its primary role is to develop a layer of isolation motion picture between the template and the concrete area to ensure that the template does not stick to to the concrete area so that it is much easier to dismantle the cast following putting and to maintain the finish of the concrete area. Here, we will unveil the types, qualities, use and program of concrete release agent in detail.
Sorts of concrete release agent
Concrete release brokers can be divided into many kinds based on different grouping strategies, and the common category strategies are as follows:
- According to the scope of use: it can be divided into concrete release agent for construction, concrete release agent for bridges, concrete discharge agent for tunnels and so on.
- According to the formula of: it can be divided into water-based concrete release brokers, petroleum-based concrete release brokers, silicone oil concrete release representatives, etc.
- According to the use effect: it can be divided into ordinary concrete release representatives, an easy task to remove concrete release representatives, high-gloss concrete release brokers and etc.
Features of Concrete release agent
A concrete release agent is additionally known as a concrete remoteness agent or mould release lubricant. It is a type of compound coated on the inner wall of the formwork to play the part of lubrication and isolation so that the concrete could be smoothly detached from the formwork when taking apart the formwork, and the shape of the concrete could be kept intact and undamaged. Compared with the standard release materials motor oil or waste motor oil, the release agent has the advantages of easy release, no pollution of the concrete covering, no corrosion of the template, effortless to paint, low price and etc. However, not all kinds of concrete release agents with a selection of supplies made of templates are suitable for different supplies of the template and different development conditions and finish requirements of the concrete must be selected for the appropriate release agent in order to receive good results.
As an important construction auxiliary material, concrete release agent has the following features:
Good remoteness efficiency: concrete release agent can develop a dense remoteness motion picture between the formwork and the concrete area, successfully stopping the formwork from bonding with the concrete surface and facilitating the dismantling.
Great lubrication performance: concrete release agent has good lubricating overall performance, which can lower the chaffing between the formwork and concrete surface, lower the resistance during pouring and boost the construction effectiveness.
Good anti-adhesion efficiency: concrete release agents can successfully avoid the formwork from bonding with the concrete area, steering clear of the formwork from damaging the concrete surface when taking apart the formwork.
Good waterproof efficiency: concrete release agent has good waterproof performance, which can successfully prevent moisture from penetrating between the formwork and concrete, steering clear of deformation of the formwork by moisture and enhancing the service life of the formwork.
Easy to use and safe: concrete release agent is easy to use; you only need to apply a layer evenly on the formwork; at the same time, it is safe and environmentally friendly and will not pollute the human body and the environment.
When using a concrete release agent, the following steps should be followed:
Prepare tools: concrete release agent is usually sprayed or brushed for construction. You need to prepare construction tools such as a sprayer or brush.
Choose the right release agent: According to the different environments, choose the right concrete release agent, such as indoor use can choose a water-based concrete release agent, and outdoor use can choose an petroleum-based concrete release agent.
Apply the release agent: Pour the appropriate amount of release agent into the sprayer or container, and then evenly spray or brush on the formwork to ensure that each part is coated in place.
Air drying: After application, wait for a period of time to allow the release agent to dry naturally. Generally, it takes 10-20 minutes, depending on the environment.
Pouring concrete: After the release agent is completely air-dried, the concrete can be poured. During the pouring process, care should be taken to avoid air bubbles or voids between the formwork and the concrete area.
Demolding: Demolding can be carried out after the concrete reaches the strength of demolding. When taking down the formwork, the connectors at the edge of the formwork should be dismantled first, and then the surface of the formwork should be knocked gently to separate the formwork from the concrete covering gradually. In case of tight bonding between the formwork and the concrete surface, tools can be used appropriately to assist in the dismantling.
Clean up the template: after taking apart the template, the template should be cleaned up to remove the residual concrete and mould release agent. After cleaning, it can be used for the next time.
Application areas of concrete release agent:
Concrete release agent is widely used in all kinds of development projects, mainly including the following aspects:
Reinforced concrete structure: In the development of a reinforced concrete structure, concrete release agents can be used for formwork isolation, stopping formwork from bonding with concrete and increasing construction efficiency and quality.
Road construction: in road construction, the concrete release agent can be used to isolate the bond layer between the road formwork and concrete area, to avoid road bubbles, hollow drums and other problems.
Bridge project: In a bridge project, a concrete release agent can be used to isolate the bond layer between the bridge formwork and the concrete area and enhance the construction quality of the bridge pier and abutment.
Tunnelling project: In the tunnelling project, a concrete release agent can be used to isolate the bond layer between tunnel formwork and shotcrete surface to improve the quality and safety of tunnel construction.
Nuclear power project: In nuclear power project, a concrete release agent can be used to isolate the bond layer between the shell of nuclear power equipment and internal components to ensure the safety and stability of the equipment.
Other fields: concrete release agents can also be widely used in water conservancy projects, wharf projects, airport projects and other fields to provide effective formwork isolation protection measures for various building projects.
In conclusion, concrete release agent, as an crucial construction auxiliary material, plays an indispensable role in modern building projects. By choosing the right sort, the correct use method and a reasonable application field, can effectively enhance the construction efficiency and quality of the development project and provide a strong guarantee for the development of the building industry.
